Specification of Letters Patent.

Patented Feb. 1, 191d.

Application filed August 26, 1909. Serial No. 514,746.

To all whom it may concern:

Be it known that I, Jnssn B. GARBER, a citizen of the United States,residing at Salem, in the county of Columbiana and State of Ohio, haveinvented certain new and useful Improvements in Valve Cages and Valvesfor Pumps; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to pumps and pumping apparatus, but has referencemore particularly to valve-cages and valves for use in pump cylinders,and to novel means for securing such cages within their respectivecylinders.

It has for its object the production of an inexpensive, durable andpeculiarly eflicient valve-cage, adapted for use in connection witheither outside or flush caps, at the foot, or at any other operativeposition, within a pump cylinder deep well or otherwise, and adaptedalso to be adjustably secured in predetermined position by means carriedby the cage itself.

The invention will be hereinafter particularly described and pointed outin the claims following.

In the accompanying drawings which form part of this application forLetters Patent, and. whereon like characters refer to correspondingparts in the several views:

Figure 1 is a longitudinal central vertical section through the lowerend of a pump cylinder, valve-cage, valve and outside cylinder-cap. Fig.2 is a horizontal section on the line 22 of Fig. 1, looking down uponthe parts shown by said figure. Fig. 3 is a plan view of valve-cagedetached. Fig. 1 is a central vertical section corresponding with Fig. 1but including a modified form of valve-cage, and Fig. 5 is a horizontalsection on the line 5--5 of Fig. 4 showing the same modification.

Reference being had to the drawings and numerals thereon, 1 indicatesthe lower end of a pump cylinder of any desired material and capacity, 2an outside cylinder-cap into which said cylinder is threaded asindicated at 3, and 4 a suitable packing interposed be tween the end ofsaid cylinder and a shoulder 5 within the cap 2. The said cap 2 isperforated centrally by a water inlet 6 and is provided with a raisedvalve-seat 7 concentrically located with relation to the shoulder 5 bywhich it is surrounded.

Normally resting upon the seat 7 is a disk valve 8 circular in form, andcushioned upon its underside by a disk of leather or similar material 9.Surmounting the valve 8 and consequently within the lower end ofcylinder 1 is a valve-cage 10 made of spring ma terial, either cast orstamped, such as brass, bronze or other metal comprising an annular base11 closely but slidably fitting the interior of said cylinder. Risingfrom base 11 are vertical cage members 12 arranged in diametricallyopposite pairs as best shown by Fig. 3 of the drawings, each pair ofrisers 12 having horizontal extensions or radial arms 13 joined at theapproximate center of the structure by an integral boss 14, as

clearly shown by Figs. 1, 2 and 3.

Each of the oppositely disposed and centrally arranged bosses 14 haveinclined upper faces 15, a beveled countersunk under surface 16, and-acentral vertical depression 17 in their opposing edges, as best shown byFigs. 1, 3. Passing vertically between the oppositely disposeddepressions 17 aforesaid is an adjusting screw 18 the head 19 whereofconforms in shape to the beveled countersunk undersurface 16 of bosses14, while upon said screw is threaded a nut 20 the opposite sideswhereof rest upon the opposing boss inclined 15, as shown by Figs. 1 and2.

The foregoing being an embodiment of my invention in its preferred form,it will be noted that the self-contained cage-locking features may bevariously modified without departing from the spirit of my invention;for example, Figs. 4t and 5 represent a modification of the presentinvent-ion applied to pump cylinders such as 1 having an inside or flushcap 2, screw-threaded as at 3% packed as at 4P, shouldered at 5 havinginlet port 6, valve-seat 7 and valve 8*. The said modified Figs. 4 and 5also disclose a valve-cage 10, 11, 12 18 having a central annular boss14L broken radially as at 14 to allow for a limited degree of expansionand contraction under action of a taper screw plug 18 the latter beingbroken by a port 18 by preference squared to facilitate turnmg.

This being a description of my invention in the best forms at presentknown to me it will be apparent that valve-cages embodying selfcontained locking features such as hereinbefore described may be readilyand accurately secured at any predetermined position within a pumpcylinder by the simple and effective means of expanding the sides ofsaid cages until they firmly engage at points diametrically opposite theinner walls of such cylinders as shown by the drawings. For example, anordinary screw driver inserted in the slotted head 19 of adjusting screw18 serves to seat said head in the countersunk under-surfaces 16, 16'ofbosses 14, 14 and simultaneously draw nut 20 down the oppositelyinclined upper faces 15, 15 to spread and forcibly wedge them apart,and, as a consequence, to force risers 12 with the outer ends of radialarms 13 into close frictional contact with the inner walls of thecylinder 1, thus retaining the cage in its proper position, untilreleased by a reversal of the operation last described.

This being a description of the present invention and a statement of itsoperation, what I now claim and desire to secure by Letters Patent is:

1. In a pump the combination with a working cylinder, a valve-seat andvalve, of an expansible valve-cage, and means for ex panding said cageto lock it in operative position within the cylinder aforesaid.

2. In a pump the combination with a working cylinder, a valve-seat andvalve, of an expansible valve-cage, and means for expanding said cageinto frictional engagement with the interior of the cylinder aforesaid.

3. In a pump the combination with a working cylinder, a valve-seat andvalve, of an expansible valvecage, and means carried by said cage forexpanding it into frictional engagement with the interior of thecylinder aforesaid.

1. In a pump the combination with a working cylinder, a valve-seat andvalve, of a valve-cage made in separable sections, and means for wedgingsaid sections apart to lock the cage in operative position by frictionalengagement with the interior of the cylinder aforesaid.

5. In a pump the combination with a working cylinder, a valve-seat andvalve, of

a yalve-cage having a cover comprising radial arms, and means forspreading said arms radially to lock the valve-cage 1n operativeposition.

6. In a pump the combination with a working cylinder, a valve-seat andvalve, of a valve cage having a skeleton cover com prising radial arms,a lug upon the adjacent ends of said arms, and an adjusting screw forspreading said lugs.

7. In a pump the combination with a working cylinder, a valve-seat andvalve, of a valve-cage having a skeleton cover comprising radial arms,lugs upon said arms having opposing beveled faces, and a wedge elementco-acting with said beveled faces to spread the arms aforesaid.

8. In a pump the combination with a working cylinder, a valve-seat andvalve, of a valve-cage having a cover comprising radial arms arranged indiametrically opposite pairs, lugs connecting each pair of said arms,and an adjusting screw for forcing said lugs apart.

9. In a pump the combination with a working cylinder, a valve-seat andvalve, of a valve-cage having a cover comprising radial arms, lugsconnecting the inner ends of said arms in pairs, oppositely arrangedinclined upper faces on said lugs, and an adjusting screw for engagingand spreading said inclined faces.

10. In a pump the combination with a working cylinder, a cylinder cap, avalve seat in said cap, and a valve, of an expansible valve-cage andmeans for expanding said cage to lock it in operative position.

11. As an article of manufacture a radially expansible valve-cage, incombination with means carried by sald cage for expanding it to increaseits diameter.

12. As an article of manufacture a radially expansible valve-cage.

In testimony whereof I aflix my signature, in presence of twosubscribing witnesses.
